"$this" is object where the function (which uses "$this") is
declared. Here is an example:
class A
{
var $aaa = "foo";
var $bbb;
function fff()
{
echo $aaa; //$aaa is a local variable
}
function ggg()
{
echo $this->aaa; //$aaa is a member of object of class A
}
function hhh($newval)
{
$aaa = $newval;
}
function iii($newval)
{
$this->aaa = $newval;
}
function jjj()
{
ggg();
}
function kkk()
{
$this->ggg();
}
}
$obj = new A; //creating object (or instance) of class A
echo $obj->aaa; //printing object member variable $aaa
//foo
$obj->fff(); //fff() prints its own local variable $aaa (no value)
//
$obj->ggg(); //ggg() prints object member $aaa
//foo
$obj->hhh("bla"); //hhh() changes local variable's value to "bla"
echo $obj->aaa;
//foo
$obj->iii("bla"); //iii() changes object member's value to "bla"
echo $obj->aaa;
//bla
$obj->jjj(); //jjj() tries to call function ggg() that doesn't exists
//!!!error!!!
$obj->kkk(); //kkk() tries to call object member function ggg()
//bla

I am having trouble with my IIS server. When I restart the site runs fine, But only
for one visit. If I leave the page or close the browser and try to return the page
cannot be found.
Can somebody explain this to me?
Thanks,
Hey all,
My php.ini file is not in the WINNT directory. But phpinfo() functions
tells me it is. Anywhere else i should look for the file. I am using .dll
file with apache 1.3.20.
Thanks in Advance,
Pritpal Dhaliwal
Looking at:
http://www.php.net/manual/en/ref.cpdf.php
Does anybody know where the patched php_cpdf.dll for windows, as
suggested above by Justin (bottom of page), can be downloaded?
Unfortunately, Justin already responded to me that he runs linux and
therefore is not able to compile a dll for windows
himself. So if somebody else with C-expertise could help me out and
put the dll for download I would be delighted.
Thanks in advance,

$this-> refers to the class itself.
So,
class myclass {
function write() {
...some code
} // end function write
function checkfirst() {
... somecode
$this->write();
} // end function checkfirst
} // end class myclass
